We want at least Marshmallow upgrade for LENOVO VIBE K5 PLUS (INDIA)

Lenovo vibe k5 plus needs a marshmallow upgrade. There is a marshmallow update but not for Asian countries.. K3 note, k5 note have marshmallow, k6 power has naught. But k5 plus is running with lolipop. Lenovo released an upgrade on may, 2017 but that was not for Indian users.... WHYYY... We demand a software upgrade to marshmallow.
